ServiceLabsOne key. One API. Every Finnoto utility.

HTML → PDF, split PDF, zip, unzip and XLS → XLSX behind a single authenticated gateway. Call any utility synchronously or as a job, get your files on R2, and see usage and latency for every key.

Sync or async — same call

POST to a utility and wait for the result, or POST to its /jobs route and get a job id back instantly. Slow sync calls turn into jobs on their own instead of timing out.

Jobs, sync & async

🔑

One auth layer

One API key works for every utility. Scope it to the utilities a service needs, give it a rate limit, revoke it instantly.

API keys & access

📈

Usage & latency, per key

Every call is tracked — requests, success rate, p50/p95/p99 end-to-end and inside the Lambda — by utility and by API key.

Usage & latency

🗂️

Files on R2

Every file a utility produces is copied to Cloudflare R2 and returned as a link, with a predictable key layout per job.

Files & storage

🔏

Signed callbacks

Async jobs can POST their result to your URL, signed with the Standard Webhooks scheme using your key's own secret.

A console for all of it

Dashboard, per-utility playground, job timelines, usage by key, API keys and members — the same look as Emithook.
